Ok, down and Dirty:
What do you gain from accessibility?
- It is the right thing to do, none of really want to discriminate, none of really want to build barriers for people to use our service or business.
- Unless you are the only person to offer a service or product, you have competition and you are likely always trying to keep ahead of them. You can offer those with accessibilities something that your competitor likely does not so they will come to you and tell their friends about you. I suspect you can not afford to turn away new customers and why not pick up those your competitor turned away as well?
- Accessibility and standards go hand in hand, both improve the chance that your site will be shown the same way in all browsers that support standards and subdue the chance of mistakes in your code that may cause problems for those with disabilities. Best to always Validate your pages.
- Accessibility and standards help future proof your site, they help to make the maintenance of the site easier and therefore cheaper and can save you money.
- Web sites built with standards and accessibility in mind are smaller and faster loading which can help lower the overhead of your site for Bandwidth use etc.
- Standards and accessibility require a logical layout which in turn improves useability, this makes the customer happy and increases the chance of a sale or repeat visits.
- This logical layout using correct semantics makes the use of the site easier to the disabled user, this certainly does not make the site harder to use for the sighted so your site is easier to use to all your visitors.
- The logical layout and the well written content you hopefully already have are great ways to rank better with search engines. However do not forget when you think to yourself that you do not have many blind users that you really have no idea how many you have but I will guarantee that you do. Search engines are blind. They do not care how nice looking your site is, they do not care if you have great flash talent. Search engines care about text and structure and nothing else. So a site that is optimised for blind visitors is optimised for search engines as well ad this can only help to raise your rankings as you help the engines serve their customers better.
What accessibility does not mean?
- Ugly text sites. A well thought out, well written, CSS and Standards based logical site can have as many nifty graphics and pretty colours as any other site. Accessibility does not mean a site must be ugly, it does not mean that you need to have a text only site for blind users. A logical simantically written site using common sense can be just as useful with lots of graphics. Accessibility is not making extra sites, it is about making good looking sites that are still use full when those images are not there.
- More money, now this depends on the developer, but a accessible site is not inherently more expensive when planned from the beginning. Making a current site accessible can be difficult and expensive. So why not just pay for a new site, develop it as a accessible site then release it with Fanfare! So you pay for a design and that will cost money, but think of the press coverage you can call up, the hoopla as you advertise your commitment to the disabled community! Invite disability support groups to test the site and improve it with their input and word will get around. The money you spend on the new design is easily countered against the press releases and possible gains you could have with a good press campaign.
- Targeted at a few blind users. As I said, you do not know how many you have and you cannot afford to ignore blind users like Google and Yahoo. World wide are millions of blind users who may wish to user your service or product and you are locking them out! But note how I began, it is not about a few blind users, what of all the other disabilities? Here are just a few …
- Dyslexics: who have trouble reading long paragraphs, justified or centred text and large complicated technical terms.
- Cognitive problems : those who may have the same trouble reading as mentioned above or be confused my scrolling text and moving graphics.
- Attention deficits: those who cannot sit through long paragraphs and technical terms or concentrate with bouncing blinking graphics distracting them.
- Epilepsy: those who suffer this may be hospitalised after visiting your site with lots of blinking moving things and “MTV in your face” style fast Flash movies. Do you really want a call from a lawyer who represents a Epileptic hospitalised after visiting your site?
- Colorblindness: is your site using colours they cannot see like red? Do you highlight important messages visually only using red text? Are your links in text only notable as such as they are red? Red on black or black on red? This is Dark Olive Green with black to many people on this planet, 1 in 10 people are colour blind and the largest group do not see red.
- Missing limbs or motoric problems like arthritis: those who cannot use a mouse to navigate and use the keyboard instead.
- Visually Impaired users who use a braille or screenreader that reads out the text over loudspeakers. Can be difficult when sites use background music or force new windows to open.
Even little things like underlining text can cause problems making the text hard to read, not to mention upsetting the user who expects it to be a link. Above are just a few of the “other” other disabilities to consider. It can also be the “sighted person” with the famous “Cola Bottle Glasses”, or the young person who broke his arm last week and cannot use a mouse or the person who simply prefers the keyboard over the mouse.
- Seeing the site as you want them too. You cannot control lighting, user agents or resolutions. So any settings can be adjusted in so many ways by the user that you cannot guarantee that your design will be seen as you wish. It is our job to make sites that are seen as closely as we can to what we wish but still look good and are usable when shown in a way needed by the user.
Simply put, accessibility is about making your site available to everyone regardless of disability, health, age, hardware or software and user agent. Making a site that works when read or seen, sites that can be adjusted through the use of CSS by the user to meet their needs. It is using common sense and offering all information in a alternative manner when not accessible (like HTML sites parallel to main Flash site for those who can not see Flash, those who do not or cannot use Flash in their user agent).
Lastly, and placed at the end as the worst reason to make accessible sites but needing mention, it is Law in a growing number of countries. The United Kingdom has the DDA. it is arguable in how much it covers web design but it does require commercial business not to discriminate. Section 508 of the United States requires Accessible web sites for all government agencies as well as all businesses that have contracts with government agencies or wish to contract with the government. Germany has a law requiring accessibility in all local and federal governmental sites. The future suggests that eventually all sites will be required by law to be accessible, so better to be in the forefront as playing follow up in a few years.
